I think in your last post you used the word "balmy." Is that some kind of Ultimate term? Because there's also a word like that meaning a sort of relaxing warmth, as in a bathtub or on a sunny beach. You obviously can't be talking about the weather, so please explain.
The correct term for the evenings, and maybe it was just a typo for you, or some kind of California slang I don't know, is "nippy". Also "crisp". Days are sunshiny and pleasant and glowing, but mornings and evenings are scarf weather, hands in the pockets and idly wondering where you stowed your gloves, and maybe it's time to head down into the basement to dig them out. See your breath mornings. Nights are great for sleeping, because you need to snuggle in under the covers for a little while before you're warm enough.
It's also dark. Getting dark early, and dark for a long time. Right now it's new enough to be all stars and clear evenings and wonder and smelling the dry leaves and thinking about trick-or-treating. Soon it gets into bleak hibernation, when-will-we-have-daylight-again mode. That's when you can taunt me. For now, this is the best time of year. Nippy. Crisp. Bright.
